Residual Current Circuit Breaker (RCCB) is an integral part of electrical safety systems, playing a crucial role in preventing electrical fires and shock accidents. RCCBs are devices designed to monitor the balance of currents in an electrical circuit and trip the circuit when an imbalance, or leakage current, exceeds a pre-set limit. This article aims to provide a comprehensive understanding of RCCBs, their working principles, and their significance in ensuring electrical safety.
What is RCCB?
RCCB, or Residual Current Circuit Breaker, is an electrical safety device that is designed to detect and interrupt the flow of current in the case of a leakage. It continuously monitors the current flowing through the live (or phase) and neutral conductors of an electrical circuit. In a properly functioning circuit, the current flowing through the live wire should be equal to the current flowing through the neutral wire. However, when a leakage occurs, such as when current escapes through a damaged insulation or when an appliance malfunctions, the balance is disrupted. RCCB detects this imbalance and trips the circuit, preventing further damage or accidents.
